Do multiple Whois changes affect organic rankings? (Escrow)

I'm selling a site in a rather highly priced acquisition deal and will be putting the domain in Escrow for a 1 year period while the buyer makes payments. I don't like the fact that the whois information would change to the Escrow company for a year and then to the buyer after the year period as I find it to be an unnecessary risk from an SEO perspective. I'm looking to not rock the boat and provide a seamless transaction from start to finish and feel the multiple whois changes might rub Google the wrong way, which may or may not have an affect on organic rankings. I've considered the option of handing over my entire registrar/hosting account logins instead of having the whois change 2X in 1 year to keep things the way they are. This is a rather significant purchase price. There will be something in the contract that specifies the payment schedule may change if traffic decreases, which is why I'm being overly cautious with anything that could disturb that. Do you find this to be a risk and how would you handle this? Thanks!
